The program shared heartwarming footage of the brave young man as he navigated life through a revolving door of hospitals after he was diagnosed at just 4 years old. In a resurfaced interview filmed before Samuels' death on October 3, Symons recalled the time doctors told him about his son's condition.

"It was the first, most awful moment of my life," Symons, 69, revealed in a previous episode of Australian Story, which aired in 2009. "I can remember calling my father in tears and saying, 'He has to have brain surgery. He's 4 years old.' Just that. It's… it's still too awful to contemplate, so I don't."

But he could not ignore Samuel's fate any longer because, despite ongoing treatment, the tumour found in his brain was only getting bigger.

"I contemplated the notion that perhaps we should 'let him go,' was the expression," said the former Hey Hey It's Saturday star. "I guess, I sort of meant we should let go, as much as let him go. Maybe he will survive this, maybe he will die. Maybe that is a better option than performing this treatment. We wouldn't have acted on it, didn't act on it, but I wondered."

Australian Story had filmed the footage between 2006 and 2009 in an attempt to show the tragic journey patients and families go through with childhood cancer. But what producers found was a remarkable young man who was "too busy" living his life than dwelling on his illness.

"I think after being so close to death that I could give it a little peck on the cheek, even then I don't tend to think about it or never have really thought about it so much, 'cause I was too busy trying to stay alive and keep living," Samuel said at the time.

"I really just didn't care about death, and never have and never will."
